For longer stuff, I actually often write in another editor and then copy and paste into my browser. Don’t know how this’d work in your workflow, but maybe keeping WordPad up with settings that work for you, and when you get ready to send your response do a fast Ctrl-A Ctrl-C Alt-Tab Ctrl-V and you’re there.

(I use Emacs for most of my typing, which is fantastic if you’ve devoted the neurons necessary to train your fingers to like it, but probably isn’t a reasonable tool for the average end-user.)
